AMD 4600 X2 showing 695MHz!
Discussion
I wonder if anyone can shed any light on a problem that’s just cropped up on our PC.
Last night, whilst the kids were playing the Sims2, the game speeded up to something like double the speed. I then tried other games, and they’re all the same, playing twice the speed they should be!
The PC has an AMD X2 4600 duel core CPU (with the Dual core hot fix already installed), a GF 7950 GPU, 2GB of memory and a fairly cheap and cheerful (after the main M2N SLI Delux mobo gave up the ghost!) Abit NF-M2P MATX mobo.
I don’t have a lot of options in the mobo BIOS, but I did manually change the setting for the CPU so that it should run at the default 2.4GHz (as before – not overclocked), but when I look at the system information and CPU-Z, the CPU reads at 690.5 MHz!
(Multiplier is X 12, Bus speed says 57.5 MHz and HT link is at 287.7 MHz)
Would anyone know if it’s the mobo or CPU at fault here, my problem being that all the other PC’s we have are Core 2 Duo’s, so I can’t swap any components to check!
Bit annoying, as I just bought TDU and an Xbox 360 controller to play it!
Can anyone help?
Cheers,

Neither, it clocks itself down depending on utilisation, pretty much like the Intel speedstep technology
Which often causes Windows to detect the speed wrong as it's always fluctuating.Best bet, undo any fiddling in the BIOS you've done (reset to factory) and then reinstall DirectX completley via a download from the Microshaft site.
Ohh, don't get your hopes up about TDU...

Nope, never seen that before, however, I have sorted it, updated the BIOS, cleared the CMOS with the jumpers, and hey presto, CPU now showing 2.41GHz!(Was a hell of a pallava though, had to rip out my floppy ffrom my work PC and connect it to the other one to install the BIOS file!)
Am installing TDU right now, will let you know..........

Off topic and sorry if it looks like a hijack but if a dual core processor is said to be 1.6GHz, does this means its total is 3.2 (2x1.6) or is it just 1.6?
No, it means that you have what are essentially 2 separate cores, and software that has been coded to use multi core CPU’s are the only ones that can take advantage (more and more new games and software are becoming available, though)I found that when playing Thief 3, the dual core was a big prob, and had to download and install a fix for it so that I could play the game!
Oh yes, TDU, it’s certainly playable, but certainly needs a patch, soon!

No, it is still 1.6, but the extra core allows it to do more work at once. For tasks that are easily split up (eg photo/video processing) it can be nearly 2x as fast, as each processor does half the work. For tasks that can't be split up it would run at the same speed as a single processor, though you still have an advantage as all the background functions (network/disk access, operating system stuff etc) can be done by one core allowing the other to do the computations.chris watton said:

The reason that it reads 690.5mhz is that your bus speed is wrong. 12 x 57.5 = 690mhz. The bus speed should be 200 and on most bios this is a user changable figure. Not sure why its been changed to that in the first place. Best thing I can suggest rather than mess about with everything, just in case of other changes, reset the bios (usually have to do this with jumpers on the board). Should then be back to normal.Last night, whilst the kids were playing the Sims2, the game speeded up to something like double the speed.

Yes, I did notice the Bus speed being very low - to be honest, I don't think the replacement (for the Asus M2N SLI mobo) Abit board is up to the job - I did clear the CMOS and update the BIOS and all's fine again - but I didn't change anything before the problem occured. I prefer the more expensive boards where you don't need a damn floppy drive to update the BIOS - I installed the boot disk and BIOS stuff on a flash drive, but there are no options to use it as a boot drive!Peter
..And there are absolutly no options to change the Bus speed, or CPU speed in the BIOS too, which quite surprised me! I'm hoping it goes again, so I can change the darn thing!

Normally the bus speed setting is hidden until you change the settings from Auto to manual. The cpu multiplyer is normally always fixed (very expensive kit needed to get this) so usually the only way to over clock is to alter the bus speed and therefore the speed of the cpu that way. The trouble is that many other settings nearly alway need to be altered too like dram timings and ht multiplyers etc.
I know about the auto/manual setting, but this board's BIOS options are the most limited I have ever seen (the complete opposite to the Striker Extrme mobo I have for the work PC!) - and with the latest BIOS update, it's even more limited, giving me no option anywhere to change the CPU multiplier, let alone Bus speed - they're not hidden, they're just not there! lolI wonder what the best MATX mobo is for my CPU, 7950GPU and 2BG of Corsair RAM, which seems to be wasted attached to such a flimsy mobo! (I bought the cheapest mobo at the time, as I needed to see whether it was the Asus mobo or CPU that was at fault when I transplanted the stuff from one PC to another)
